' A ppli'cationfiled .Tu1y22,1922, Serial No. 576,679

Toall 'wlwmz't may concermr H Be it known that I, MARCUS B. BEHRMAN,

a citizen of the United. States, and a resident of New York a city,

certain J new and useful Improvements 7 in Lather. Brushes, of whichtheifollowin'g,v is a specification. I 1

Theinvention relates toim provements in 'latherbrushes-of thetype comprising a handle, a ferrule receiving v the threaded shank of the handle and. a bunchof bristles orthe likerbound together at the knot end thereof" and; permanentlysecured: within the lower of the bunch .of bristles being permanently, secured within'thei -ferrule,-,.the bunch may not be subjected from time to time, as may a be necessaryor desirable,-to the process of sterilization without injury to the ferrule.

In many instances also: the handle has been.

' permanently/secured. to the ..ferrule, ;and

hence obviously the brushf could not be subjected to a boiling process for-the urpose of sterilizing the bristles'without injury to both the ferrule and- ,handle; structions of lather brushes .1 have :also been well-known.

In accordance with present -invention I provide aferrule and a, bunch for br stles whose knotend is seated within the ferrule in a mannerpermitting ;ofthe separation, whenever desired, of the bunch of. bristles from the ferrule, and I secure thefbunch of bristles in rigid,relationtojthe ferrule by means of a Y threaded head having a. central vertical operating stem by means, ofwhich the'head may be screwed into the ferrule and against the knotendof the bunch with sufficient firmness tobindthe bunch of brist es i ltfixed relation to the ferrule. The handl for. theb-rush is screwed into; the outer end of the ferruleand is chambered to pass over. the operating stem on the binding head; Oneadvantage-,-of my invention is that the head which'is screwed against-the knot end of thebunch ofbristles is a flatsolid headciidisk. I characterwhich-maybe screwed to position either. with the use:of;a-.screw-driver or manually with-the thumban-d finger-and that said head lies low down; in the: ferrule and does not *interfere'with the: screwing of the shankend of-thehandle into the ferrule in in the county of New, York and. State of New York, have invented 5 panying drawings, 1 in which Other conand inwardly teriorseating,

the usual and ordinary way. The." handle is not subjected, in accordance "with my in- .vention, to'any strain so far as .securing'thei.

bunch of bristles in place is; concerned. I; illustrate in the accompanying draw 1 ings a preferred embodiment'o fmy inven- Ihowever, in every in; to all of the details and tion, not intending, stance to be limited proportions of the "parts thereof shown, and

the invention will be fully understood from" the detailed description hereinafter pre sented, reference being had to the accom Fig. 1 is a side elevation of a lather brush; constructed in accordancewith and embodying the-invention; i

Fig. 2 is a centralthe same, and v Fig. 3 is a side elevation, artly in section and partly broken away, showing the several parts of the brush as juxtaposed' for assent, blyd t; produce the brush shown in Figs. 11 an a a vertical section through In the drawings, 10 designates the handle,

11.,the ferrule and "12' the bunch of bristles or the like, the knot ends of the bristles be-H ing firmly secured together by rubber; or other material to formr akn t liylwhich is closely encompassed by a securing metal band 14- whose sides converge downwardly inwardly inclined andslightly-convexed ex;

around the band. i The handle 10 may YSuitableoutline adapted to be Conveniently grasped and form .a downwardlyzand surface. extending entirely by thehand, and said handle. at asuitable;

. distance below itsupper end is. formedwith an annular shoulder. 16, below whichlthe handle is constructedwitha threaded portiongor shankend l7. Within the handle 10 is formed a verticalchamber 18 which ex tends upwardly from the lower.end of the,

portion 17a suitable distance for serving-the purposes hereinafter described. The handle 10, except for the presenceof the chamber 18, may be considered of ordinaryconstruction,

The ferrule 11 has a. screw-thread 19! ex; tending downwardly to near. the I lower endof'the ferrule, and below this. thread 19 the. ferrule. is formed with a chamber to receive the band 14: on theknotend-ofthe bunch and With an opening 20 through which the bristles of the bunch projeQt -and which is bee 18 thereof will slip downwardly overi in rigid relation to the ferrule.

23' ma y' be screweddownwardly into the male eithnmanuall y, as by the thumb and-"finger applied td-the -s teni 25, or means of a screw-driver ap lied to the slot surrounded by a vertical wall 21-extendingbelow the lower edge of the hand l t-andclosely engaging the bristles adjacent to said band. Within the chamber at the lower end of the ferrule 11 is formed an annular shoulder 22 which is at the upper end of the opening 20 and extends laterally therefrom and serves as a seat for the lower edge of the band 14, whose upper portion is disposed within the lower chamber of the ferrule and terminates adjacent to the lower end of thethread 19,- asshown in Fig. 2.

The'bun'ch ofbristle's is introduced downwardly through the ferrule 11 and the band 14 seats itself upon the-shoulder 22, and thereupon myinvention provides means for bindingf'the bunch in rigid relation to the ferrule, said means comprising a binding head or disk 23-which is formed with a pe rip'h'ei'al screw-thread 2 .1: and has a central upwardly extending operatingstem '25, this stempreferably being formed at its upper part with a milled surface 26 and'a screwdriye'rfslot 27. The binding head 23 and its formed of any suitablema terial and I have found it convenient to make "the same in one integral piece of metal. The binding head 23 is adapted to be screwed into the thread-19 of the ferrule and d'own' against the upper end of the-knot 13 a ndband14or to the position shown in Fig.2, and when in'this position the head 23 firmly binds the band 14 against its seat 22 andthereby secures the bunch of bristles The head "'27-in's'a1d stem; I prefer to make the stem 25'of substantial length, as "shown, so that it may be providedwith'the milled surface 2 6 for convenience inmanually positioning and removing the head 23. After the bunch of bristles has been secured in place by means of the head 23, the handle 10 may th'enbe screwed into the'u'pper or outer end of the ferrule 11 "inthe usual way, and in applying the handle to position the chamthe upwardlyprojecting portion of the stem 25 ."sai'd stem being less in diameter than the chamber 18 and therefore not interfer-' ing'with the application of the'handleto p0- sition in the or dinary' way.

Should it be desired to separate the parts of-the brush for the purpose, for illustra-- tion, of sterilizing the bunch of bristles, the handle will'be unscrewed from the ferrule and't'he binding head 23 will then be unscrewe'd froni the ferrule and consequently away from'the bunch, 'after which, byre= versin'g the ferrule,"the bunch of bristles be caused to drop thro'u'gh' the'norr'nally may upper'end thereof? After the bristles have been sterilized,- the; parts of the-'brush may be-again assembled, the bunch being introduced downwardly through the ferrule 11 until the band 14 seats itself against the shoulder 22, and the binding head 23'tli'f1" being applied to position, after which the handle 10 will be restored to its position as before.

TlleStGlll 25 may be of any length desired but preferably should be of the character 7 shown. With less convenience the stem 25 5! may be short, and in that event it would'on the positioning of the'binding' disk-pass into the ferrule beyond-thegrasp' of the fingers and a screw driver or the-like would have to be appliedto the stem for finally binding the disk against the knot of the bunch. 1 i
